A terminal is disclosed that includes a processor, coupled to a transceiver, that monitors a PDCCH (Physical downlink control channel) candidate in a first search space during a random access procedure. The transceiver receives a random access response or a PDSCH (Physical downlink shared channel) for contention resolution from a base station, based on information included in the PDCCH candidate. The transceiver receives a PDSCH or transmits an uplink signal based on information included in a PDCCH candidate monitored in the first search space, until a second search space of a type other than the first search space is configured after the random access procedure is completed. In other aspects, a base station, a communication method, and an apparatus are also disclosed.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The terminal as claimed in claim 1, wherein the processor starts to monitor the first search space from a time point of starting a window for receiving the random access response or a time point of starting to monitor a PDCCH candidate, and wherein the processor uses a PDCCH candidate including CRC (Cyclic redundancy check) scrambled by RA-RNTI (Random Access-Radio Network Temporary Identifier) for receiving the random access response.
3. The terminal as claimed in claim 1, wherein the processor terminates monitoring the first search space at a time point of having the second search space configured.
